“Ghost Town” is a sweet romantic comedy that plays off of the “seeing dead people” theme. Ricky Gervais plays a self-involved, sour-puss dentist who goes in for a routine colonoscopy. When he comes out or the procedure, he inexplicably can see, and communicate with, the dead. Of course the dead are thrilled, and start hounding him for favors. Greg Kinnear plays one of the ghosts who pesters him to keep his wife away from her new fiance. Tea Leoni is the wife, who the dentist ultimately falls for. Lots of laughs, and a warm inspirational message to wrap the whole thing up. I liked it a lot.
